m00dawg Posted February 2, 2009 Report Share Posted February 2, 2009 To give you some background here, the reason you cannot supply a regulator the same voltage it outputs is that regulators need 1-2V above what they output in order to function. So if you supply a regulator 5V and it's supposed to output 5V, it will likely output 0V :)The bridge rectifier also drops your voltage because it is just 4 diodes arranged in a clever way to cut out the oscillations of AC. So instead of having a +/- sine wave, you have a sign way at 0 and + which, with filtering capacitors and regulation, gives you DC. Diodes generally cause a voltage drop of something like .5-1.5V (I could be slightly off there - Wikipedia that if you want to know more :) so if you supply a diode with 5V, you might end up with 4.5V.Anyways, glad to hear it's working! I second using a C64 case. Wilba's design in the Pac-10 is nothing short of awesome, but I'm wanting mine to have a more vintage character. At least, that's my plan for now. Another idea was using a translucent case or something cool like that. Point is, you have a ton of options! Quote Link to comment Share on other sites More sharing options...

Flemming Posted February 3, 2009 Author Report Share Posted February 3, 2009 Feeling a lot braver after finally experiencing some success I hooked up another SID to the core - now i'm in stereo-land :) I had to shuffle through the presets once more to discover what i've missed out on... i'm baffled :) it sounds even better!!! My SID sound fetish sure gets satisfied this way.... and a bit more ;) Quote Link to comment Share on other sites More sharing options...
Futureman Posted February 4, 2009 Report Share Posted February 4, 2009 Congrats!Yea, 2 SIDS's in stereo sure is pretty damn cool.. I even really dig the poly mode in stereo (6 voices) bouncing around.. RegardsMike Quote Link to comment Share on other sites More sharing options...

RegardsMikeMan, i really want to do that!!! ... but i have no control surface yet :(Oooh ;) preset 16 in the 'vintage bank' is just fine i see..

Flemming Posted February 5, 2009 Author Report Share Posted February 5, 2009 I've been playing with my baby SID box for a few days without experiencing any problems. I'm more than happy and somehow ready to go on, so i connected my DINx4 (from Mike) to my core. Using a forcep i can now surf the menus of the synth :) it's pretty hard though, not knowing pin numbers and being totally unfamiliar with the menu layout in general. I try to refer to the sourcecode to guess the pins, but it's not the best way, i know :) But i think i recall seeing a MIOS application that showed the pin number in the display when activated?? i looked around but it's not in the MIOS download section... was i dreaming or did such an app actually exist ??

stryd_one Posted February 5, 2009 Report Share Posted February 5, 2009 IIRC MIDIO128 does, and there are test apps too. Quote Link to comment Share on other sites More sharing options...
Flemming Posted February 5, 2009 Author Report Share Posted February 5, 2009 Nice :) though the only clue i've dug out is a mention of an app called 'ain64_din128_dout128_v2_0' on this page http://www.midibox.org/dokuwiki/doku.php?id=changing_din_pins'I'll have a look at MIDIO128 ;) Quote Link to comment Share on other sites More sharing options...
Flemming Posted February 5, 2009 Author Report Share Posted February 5, 2009 I had no luck with MIDIO128.. i got a lot of 'note on' and 'note off's with velocity pretty much fixed around 128, 64 and 0 :)But i think i'm sorta sorted out, hehe.. playing with my forcep and experimenting with the 8580 sourcecode gave me a pretty good feel for the available possibilities. Right now i think i'll go for a simple minimal surface with SID L/R selector instead of core selector (it's only a 1core stereo box) and if i manage to hook up 2 respective LEDs to jp5 of the core i will be pretty satisfied with the result considering it's my first build :) Quote Link to comment Share on other sites More sharing options...
